My Grandfather, Robert K. Chittle, WWII veteran, of Flint, Mich, found a wallet in a parking lot in 1947. It contained $1,300 - which in today's dollars is $12,500. He managed to find the owner and return the wallet and the money.
The man who lost the wallet was a UAW member, and the union wrote my Grandfather a thank-you letter.
In this video he recalls the events from over 65 years ago.
I got pretty choked up when I read the letter and heard him tell the story first hand, which I think caught him off guard and thus he got a little choked up too.
